Former Arsenal youngster Chris Willock rejected the chance to join Premier League rivals Tottenham and Manchester City before leaving the Gunners over the summer.
Portuguese outlet A Bola report that the player had offers before taking his career abroad and joining Benfica.
Willock was the latest in growing list of young English players to move to a foreign side in the search of a clearer route to first-team football.
He follows the likes of Jadon Sancho and Reece Oxford, with the former turning down a professional deal at Manchester City to join Borussia Dortmund.
The report claims that there was also interest in his services throughout the summer, with a number of Premier League teams looking to take him on loan, but he opted to stay in Portugal.
Willock is yet to make his competitive first-team debut for the Portuguese side but is a regular for their B team.
